Document those early edits, and who made them and when?
If you can't then all you have is an unfounded claim with no evidence to back it up.
First, who? The Church Fathers.
Second, a clear example of editing ot the gospel Matthew ending to support the Trinity. Matthew 28:18 was added and edited.to include ' . . . in the name of the Father, the Son and the Holy Ghost.'

Matthew 28:19
Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit. (NIV)
1. Eusebius (c. 260—c. 340) was the Bishop of Caesarea and is known as “the Father of Church History.” Although he wrote prolifically, his most celebrated work is his
Ecclesiastical History, a history of the Church from the Apostolic period until his own time. Today it is still the principal work on the history of the Church at that time. Eusebius quotes many verses in his writings, and
Matthew 28:19 is one of them. He never quotes it as it appears today in modern Bibles, but always finishes the verse with the words “in my name.” For example, in Book III of his
History, Chapter 5, Section 2, which is about the Jewish persecution of early Christians, we read:
But the rest of the apostles, who had been incessantly plotted against with a view to their destruction, and had been driven out of the land of Judea, went unto all nations to preach the Gospel, relying upon the power of Christ, who had said to them, “Go ye and make disciples of all the nations in my name.”
Again, in his
Oration in Praise of Emperor Constantine, Chapter 16, Section 8, we read:
What king or prince in any age of the world, what philosopher, legislator or prophet, in civilized or barbarous lands, has attained so great a height of excellence, I say not after death, but while living still, and full of mighty power, as to fill the ears and tongues of all mankind with the praises of his name? Surely none save our only Savior has done this, when, after his victory over death, he spoke the word to his followers, and fulfilled it by the event, saying to them, “Go ye and make disciples of all nations in my name.”
Eusebius was present at the council of Nicaea and was involved in the debates about Arian teaching and whether Christ was God or a creation of God. We feel confident that if the manuscripts he had in front of him read “in the name of the Father, and of the Son and of the Holy Spirit,” he would never have quoted it as “in my name.” Thus, we believe that the earliest manuscripts read “in my name,” and that the phrase was enlarged to reflect the orthodox position as Trinitarian influence spread.
2. If
Matthew 28:19 is accurate as it stands in modern versions, then there is no explanation for the apparent disobedience of the apostles, since there is not a single occurrence of them baptizing anyone according to that formula. All the records in the New Testament show that people were baptized into the name of the Lord Jesus, just as the text Eusebius was quoting said to do. In other words, the “name of Jesus Christ,”
i.e., all that he represents, is the element, or substance, into which people were figuratively “baptized.” “Peter replied, ‘Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins’” (
Acts 2:38). “They had simply been baptized into the name of the Lord Jesus” (
Acts 8:16). “So he ordered that they be baptized in the name of Jesus Christ” (
Acts 10:48). “On hearing this, they were baptized into the name of the Lord Jesus” (
Acts 19:5). We cannot imagine any reason for the Apostles and others in Acts to disobey a command of the risen Christ. To us, it seems clear that Christ said to baptize in his name, and that was what the early Church did."
